在上一篇博客[ Spring源码学习--ClassPathXmlApplicationContext（一）][Spring_--ClassPathXmlApplicationContext]我们简单介绍了ClassPathXmlApplicationContext，接下来我们介绍一下FileSystemXmlApplicationContext

ApplicationContext应用上下文体系如下：

FileSystemXmlApplicationContext的源码如下：

/**
     * 并没有太多具体的操作，很多初始化操作都在其父类中
     */
    public class FileSystemXmlApplicationContext extends AbstractXmlApplicationContext {
    
    	public FileSystemXmlApplicationContext() {
    	}
    	
    	public FileSystemXmlApplicationContext(ApplicationContext parent) {
    		super(parent);
    	}
    	public FileSystemXmlApplicationContext(String configLocation) throws BeansException {
    		this(new String[] {configLocation}, true, null);
    	}
    	public FileSystemXmlApplicationContext(String... configLocations) throws BeansException {
    		this(configLocations, true, null);
    	}
    	public FileSystemXmlApplicationContext(String[] configLocations, ApplicationContext parent) throws BeansException {
    		this(configLocations, true, parent);
    	}
    	public FileSystemXmlApplicationContext(String[] configLocations, boolean refresh) throws BeansException {
    		this(configLocations, refresh, null);
    	}
    	public FileSystemXmlApplicationContext(String[] configLocations, boolean refresh, ApplicationContext parent)
    			throws BeansException {
    		
    		//调用父类的构造函数
    		super(parent);
    		//设置配置文件的地址，如application.xml
    		setConfigLocations(configLocations);
    		if (refresh) {
    			//刷新容器，其实就是重新初始化容器
    			refresh();
    		}
    	}
    	@Override
    	protected Resource getResourceByPath(String path) {
    		if (path != null && path.startsWith("/")) {
    			path = path.substring(1);
    		}
    		return new FileSystemResource(path);
    	}
    }
